RETAINING-SLUG FOR PRINTERS TYPE-FORMS.

Specification of Letters Patent.

Patented July 12, iaio.

Application filed April 6, 1910. Serial No. 553,745.

To all whom it may concern:

Be it known that I, JACKSON Srrvnns, a citizen of the United States, and a resident of Escondido, in the county of San Diego and State of California, have invented a new and Improved Retaining- Slug for Printers Type-Forms, of which the following is a full, clear, and exact description.

The invention is an improvement in retaining slugs for printers type forms, and belongs to that character of such devices as are provided with a continuous groove to receive the page cord.

The invention has for its purpose to provide in connection with this groove, cord tying grooves sunk in the front of the slug or rule and arranged to retain the ends of the cord.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a plan of a chase having several forms clamped therein, each provided with slugs or retaining plates constructed in accordance with my invention; Fig. 2 is a perspective view of one of the forms having the retaining plates bound thereabout; Fig. 3 is a perspective View of a corner of the slugs or retaining plates; Fig. 4. is a fragmentary horizontal section through one of the forms; Fig. 5 is a cross-section on the line 5-5 of Fig. 1; Fig. 6 is a face view of the intermediate section of the bottom retaining plate; Fig. 7 is a similar view of one end section of the said plate; Fig. 8 is a like view of the other end section of the said plate; Fig. 9 is a plan of the section of the retaining plate shown in Fig. 6; Fig. 10 is a face view of one of the side retaining plates or slugs; Fig. 10 is a plan of the side retaining plate shown in Fig. 10, the same being shown partly in section; Fig. 11 is an end view of the same; Fig. 12 is a section on the line 12-12 of Fig. 10; Fig. 13 is a sectional view similar to Fig. 12, showing a modified form of the retaining plate or slug; Fig. 14 is a like section of a still further form of the plate; Fig. 15 is a face view of the retaining plate or slug shown in Fig. 16; Fig. 1G is a cross-section of the retaining plate shown in 15, provided with a border type; Fig. 17 is a plan of a further form of the invention, with the side retaining plate spaced from and unbound to the form; Fig. 18 is a cross section of one of the side retaining plates as is used in connection with the form shown in Fig. 17; Fig. 19 is a section similar to Fig. 18, showing the retaining plate or slug provided with a border type; Fig. 20 is a face view of a modified form of the side retaining plate or slug; Fig. 21 is a like view of a modified form of the end slug; Fig. 22 is a like view of another form of end slug; Fig. 23 is a modified form of the central section or portion of the end slug; and Fig. 24: is a sectional plan of a corner slug.

Referring more especially to Figs. 1 to 12, inclusive, the forms of printers type are held together by slugs or retaining plates around which is wrapped a number of times, a cord or other flexible member 20. These retaining plates or slugs, as is the usual practice, comprise side plates 21, 21, an upper end plate 22 and a lower end plate 28,

these plates being made in variable lengths and widths to accommodate forms of different dimensions, as is the usual practice, the lower end plate being preferably made of an intermediate section and end sections, as respectively shown in detail in Figs. 6, 7 and 8. The plates or slugs instead of each presenting a plain uninterrupted surface are each provided with a longitudinal cord groove 21 located substantially on the longitudinal center at the outside. The central section of the lower end retaining plate 23 is vertically grooved from the groove 24 at points substantially separated, as indicated at 25, the adjacent edges of the grooves being undercut, as shown in Fig. 9, to bind the free end of the cord and thus provide a tie to keep the cord from unwinding. The depth of the groove 24 in each of the slugs or retaining plates is such as to insure the cord lying at the inner side of the plane of the outer face of the slug, as shown in Fig. 5, so that the forms can be clamped flat together in the chase, or, if desired, a border .type 26 clamped flat between them. The corners of the slugs are beveled downwardly and inwardly and the lips forming the undercut portion of the grooves 24 removed, as shown in Fig. 4:, so that the cord will tend to force these portions of the slugs and plates inwardly and will be well contained within the outline of the plates.

In Figs. 13 and 1st I have shown a slight modification of the cord groove. In the retaining plate 21 shown in Fig. 13, the inner wall of the groove 24;, corresponding to the groove 24, inclines downwardly and inwardly, and in the retaining plate or slug 21 in Fig. 14, the cord groove 24 is of rounded form.

In Figs. 15 and 16, the side retaining plate 21 is provided at the upper edge with a printing border 21*, the remaining portion of the construction being the same as that illustrated in Figs. 10 to 12, inclusive. In order to have the printing of the border take place centrally between the forms without using a separate border type for this purpose, as shown in Fig. 5, I have shown in Fig. 17, a form secured as in Fig. 2, except the cord is not wrapped about the side retaining plates, the cord passing the full length of the form against the type, these windings of the cord on adjacent forms being received by a single slug or retaining plate 21, which has a cord groove 249 at each side, the retaining plate in Fig. 18 being shown plain at the top, and in Fig. 19 with a border type 21".

In Fig. 20, I have shown the side retaining plate or slug 21' divided transversely into three separable sections, similar to the sectional end retaining plates, and in Fig. 21 the end retaining plate or slug 22 is made in one piece. Fig. 22 shows a form of the end slug 22 in which the groove 25*, corresponding to the grooves 25, extend both above and below the groove 24, the slug being cut out at the bottom edge under the grooves 25*, so that the windings of the cord through the grooves 25 will not interfere with the form seating flat on a surface.

In Fig. 23 is shown a form of end slug, or central section of such slug 2 t this slug having a number of cord retaining grooves 25 extending from the groove 2 & through the top edge.

Fig. 24c shows a corner slug 2%, compris ing a portion or section of a side slug and a portion or section of an end slug.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1. A printers slug for retaining a printers form, having a longitudinal cord groove in the outer face thereof, with cord tying grooves leading from the cord groove through the edge of the slug.

2. A printers slug for retaining a printers form, having a longitudinal cord groove in the outer face thereof, with cord tying grooves leading from the cord grooves and sunk in the face of the slug.

In testimony whereof I- have signed my name to this specification in the presence of two subscribing witnesses.

JACKSON STIVERS.
